Ravīndra-svarūpa: . . .the cells, because they say that the cells are the fundamental unit of life, and if they can understand even a very simple cell, then they think perhaps they can find the principles to understand everything living.
Prabhupāda: Well, this "perhaps. . ."
Ravīndra-svarūpa: But they can't understand the cell.
Prabhupāda: Yes. So their "perhaps," "maybe," is going on. And that will continue.
Ravīndra-svarūpa: Why does the living entity wish to speculate in this way?
Prabhupāda: He has been given a special advantage to think of God, but instead of thinking God, he is thinking all these rubbish things, which he will never be able to fulfill. Misusing. The thinking power he is misusing.
Ravīndra-svarūpa: So this mental speculation, or this "perhaps" and "maybe," is a misuse of his specific power to understand God.
Prabhupāda: Yes, yes. Athāto brahma jijñāsā. The life, human life, is meant for enquiring about God, and God is explaining Himself about God. Instead of studying Bhagavad-gītā very scrutinizingly, they are wasting time: "The cells, this, that, atom." That's all, wasting time. Just like we are driving this car. So we can utilize it for going from one place to another. So there is no need of studying how the car is moving, how many parts are there.
Ravīndra-svarūpa: But still, people seem to have always a curiosity about these things.
Prabhupāda: Yes. That curiosity is explained in the Bhagavad-gītā, that it is a machine, and there are many subtle parts of the machine. So you have been given this machine. You utilize it properly. Why you are busy in studying the different parts? The different parts are there undoubtedly, but you cannot actually understand.
